CARDING-ENGINE.

Specicaton of Letters Patent.

Patented Dec. 21, 1909.

Application led April 3, 1909. Serial No. 487,775.

To all 'whom 'it may concern:

Be it known that I, ELIJAH ASHWORTH, a

subject of the King of Great Britain and Ireland, residing at the Moss Brook Works, Collyhurst, Manchester, in the county of Lancaster, England, machine-maker, have invented new and useful Improvements in and Applicable to Carding-Engines, of

. the locking arrangements and to make same more compact, and I propose to have incorporated with the lock mechanism but one locking lever and to permit a partial movement thereof when the strap is shifted to the vloose pulley but to resist, by obstructing means, a full movement until rotation of the cylinder has ceased. In other words partial unlocking only is possible so long as the cylinder revolves, because the locking lever cannot make its required full movement due to the presence of the obstructing means.

An important point resulting from the use of the mechanism to be described lies in the fact, that, in the event of complete unlocking, the door itself always remains free and can be opened and closed at will from either side of the card, no locking hold resulting on the mere shutting of the door so long as the locking lever remains fully out.

The drawings illustrate and serve to eX- plain the invention.

Figure 1 is a front elevation indicating so much of a carding engine as is requisite and shows my locking means in position. Fig. 2 is a plan view partly in section. Fig. 3 shows in end view a modified form of segmental bar mounted on the locking lever. Fig. 4 shows in plan view the locking lever, a form of segmental bar and a modified form of attached plate necessary where the segmental bar has to make considerable movement prior to encountering the obstructing device. Fig. 5 shows the housingA inclosing the obstructingdevice. Fig. 6 is a side view, and Fig. 7 a plan of parts seen in Fig. 5. Figs. 8, 9 and 10 show in side, end, and plan view the obstructing tumbler. Figs. 1l, l2 and 13 are diagrams, the first (Fig. 1l) indicating the locking lever linger in the position it occupies when the door is fully locked, the second (Fig. 12) a partial unlocking permissible with the belt .on the loose pulley, and the third (Fig. 13) a complete unlocking only possible with the belt on the loose pulley and with the cylinder absolutely at rest.

According to my invention I use a locking lever a, pivoted at a to a bracket I; bolted to the wall of the bend or otherwise. This locking lever a has bolted to it at c a segmental barc and has also a pendent finger Z riveted or otherwise secured in position at the opposite extremity. I use a sliding bar e passing through the flange 3 (or otherwise guided) and havinganotch or gap e with which notch or gap e the pendent finger Z cooperates. Toward the other end of the bracket b and at the back of and near the rim of the fast pulley f, I secure a housing g having an entrance slot g the housing being attached to the bracket b by a stud g3 or otherwise. Within the housing g is an obstructing tumbler h, pivoted at h', and spring-pressed or loaded to normally resist a full movement of the locking lever a such as would wholly disengage the pendent finger Z from the notch or gap e in the bar c. The locking lever a has formed on or attached to it a small fiat plate z' which may be adjustable and is secured by the stud z" and has a nose or operating piece 2 which, when the locking lever is drawn forward by the attendant, enters the slot g in the housing and so meets the obstructing tumbler h in its normal position which accordingly checks further advance (see Figs. 6 and 8). The left hand position of the plate in Fig. 6 is the position it occupies upon meeting the obstructing tumbler in the normal position of said tumbler. The little housing g has a frontaperture or entrance slot g2 which may be masked or shrouded by the flange of the fast pulley f but preferably by a slotted ring j applied thereto, and secured by screws jl or otherwise, and so long as the main cylinder and v pendent finger cl.

fast pulley f revolve this aperture or slot g2 in theliousing g cannot be got at. When the motion ofthe main cylinder ceases, ac-

cess canbe had, and a .nail or pencil suchA as 7c (Fig. 6) can be passed through one of the slots y'2 in the ring and the aperture or slot g2 in the housing g, to encounter the obstructing tumbler h and upset or tilt the tumbler. Vhen this occurs, and the obstructing tumbler is tilted, its nose 71,2 is lowered, out of the way, and the nose i? of the small plate z' can be moved forward or advanced to such an extent that the pendent finger 6l is moved entirely clear of the notch or gap e in the bar e and thus the door D is 'left entirely free. The right hand position of the plate 2 in Fig. 2 is the position it assumes after the nose h2 of the obstructing tumbler is removed from its path.

It will be seen that the arrangement proposedisv most compact and neat, and sums itself up practically into one locking lever a with barsegment c, its supporting bracket ZJ, and parts carried thereby, and with the addition of the slotted masking ring y'. A point of importance lies, in the fact, that, after a vfull unlocking, and so long vas the segmental bar remains obstructing the strap ron the loose pulley, the door Dis entirely free and can be opened and closed from either side by a mechanic just as though no locking means were present.

It is obvious that I may vary the form of obstructing tumbler which normally resists the complete disengagement of the pendent locking finger el.

'The Fig. l2 shows the relative positions of the bare and the pendent finger d, with the segmental bar drawn out or advanced and the strap on the loose pulley. Fig. 13 goes farther than Fig. n12 and shows the complete vdisengagement of sliding bar e and Opening of the ldoor D on release, results in the forward edge ai of the pendent finger Z getting'in the rear of the bar cV and so it becomes apparent the door must be closed before the pendent finger CZ can again enter the notch or gap e', and, until such finger Z does enter the notch e the segmental bar c cannot retreat or be pushed back to the position seen in Figs. 2 and l2 and so remains advanced and held and thus acts as a positive obstruction ren- .dering it impossible to put the belt back angle-piece and I may arrange to be able to turn same against the action of a spring through approximately 90 to facilitate the x placing in position of `the belt.

It will be understood thatthe driving belt lies in the path'of the segmentalbarc andV when this bar is moved outwardly the belt is moved from the fast to the loose pulley.

I declare that what I claim is:

l. Locking means for carding engine doors, comprising a locking lever, means yintermediate of the same and the door to be locked,

said means being engaged by said locking lever, belt shifting means in connection with said locking lever, and housed obstructing means normally resisting a full unlocking movement of the locking lever a masking device for masking said obstructing means as set forth.
